Katherine Heigl jumps into the pool at friend`s wedding

Los Angeles: Though it was not her big day, `Grey`s Anatomy` star Katherine Heigl was the center of attention at her friend`s wedding after she jumped into the pool during the reception.

The blonde beauty was the bridesmaid at `Perfect Couples` star David Walton and `Roswell` actress Majandra Delfino`s wedding, reporting Us magazine online.

As about 200 guests looked on, Walton, 32, and Delfino, 30, exchanged their "I do`s" at Trinity Cathedral here and after the ceremony the party moved to a club for a reception, dinner and poolside after-party.

Heigl, a fellow `Roswell` alumni, gave a funny speech and jumped in the pool in her bridesmaid finery at the party where actress Ali Larter was also among the guests.

The celebrations didn`t end there and in lieu of the traditional champagne toast, wedding guests did a shot of tequila to cheer the newly weds.
